Definitions
- the invention relates to an arrangement with a transponder and a metallic component associated with the transponder.
- transponders are used to identify and later identify goods and other objects. These are communication devices that are able to communicate with a communication device. In this case, the communication preferably takes place wirelessly. In an often used form of a transponder, communication takes place by means of high-frequency or radio signals. Such transponders are referred to as high-frequency transponders. If these are designed for identification purposes, they are so-called RFID transponders (RFID - "Radio Frequency Identification").
- An RFID transponder usually comprises a transponder chip and an antenna.
- electromagnetic signals are received and converted into electrical signals, which are then transmitted to the latter via a connection between the antenna and the transponder chip.
- the electrical signals can then be evaluated in the transponder chip to obtain information about an identification request, for example.
- the transponder chip generates further electrical signals, which are transmitted to the antenna and converted by the latter into radiation-capable electromagnetic signals.
- the document DE 202 14 099 Ul discloses a beverage container to which such a transponder is attached, which has stored information about the beverage container and its contents.
- the document DE 298 21 877 U1 describes packaging containers to which a transponder is attached in each case by means of a special holder. Mounts are presented, which ensure a secure, shock-free as possible holding the transponder on the packaging container.
- RFID transponders Compared to a marking of objects by means of non-electronic means, for example by means of a bar code, RFID transponders have the advantage that they can be detected by means of the computer. Communication device can then communicate via a high-frequency connection, when the RFID transponder is arranged in the object or otherwise obscured, so that a visual identification is not possible. Furthermore, an information stored in the RFID transponder information can be changed or supplemented at any time.
- the object to be marked comprises a metallic component or is formed entirely of metal
- the functioning of the transponder may be impaired since the metallic component absorbs at least part of the electromagnetic energy from the electromagnetic signals to be received or transmitted.
- the metallic container forms a Faraday cage, which substantially suppresses communication between the transponder and an external device.
- the metallic component In order to solve the problem of functional impairment by the metallic component is trying to attach the transponder or at least its antenna as possible so that a maximum distance between the metallic component and the antenna is present. This is achieved, for example, by attaching the transponder to a surface of the metallic component by means of a very thick adhesive film.
- the results of such an approach leave something to be desired, especially since the application of a thick adhesive layer causes the transponder protrudes from the surface of the metallic component.
- an arrangement with a transponder and a transponder-associated metal component wherein an antenna for the transponder is formed by means of a recess in the metallic component.
- the formation of the antenna by means of a depression in the metallic component has the advantage that the emission characteristic of the antenna can be determined essentially by the configuration of the depression.

Simplified, the operation of such an antenna, which formed by means of a breakthrough 5 in a metallic component 1 will explain as follows. In essence, the aperture 5 represents a negative image of a dipole antenna.
- the metal of the metallic component 1 The polarity of the electric field (E field) and the magnetic field (H field) of an electromagnetic signal radiated from or received by the antenna is thus opposite to the ratio at one This property of the antenna can be taken into account when aligning an antenna of a communication device used as a reading and writing device.)

Furthermore, the transponder 2 comprises flat metal elements 11, by means of which between the transponder 2 and the antenna formed by the recess 3 in the metallic component 1, a capacitive coupling is made. The capacitive coupling arises because the flat metal elements 11 form a capacitor with the metallic component 1.

- Information about the geographical position of the metallic components 1 can be stored in the transponder 2.
- the transmission of this information by means of electromagnetic signals can take place via radio networks, in particular mobile radio networks, for example via a GSM network, a UMTS network or the like.
- the transponder 2 is completely arranged in the recess 3 and fixed there by means of an adhesive layer 14 on the metallic component 1.
- the flat metal elements 11 pierce the adhesive layer 14 when attaching the transponder 2, so that a galvanic contact is formed, which is necessary in terms of the connection 6 between the antenna and the transponder 2.
- This type of attachment has the advantage that the transponder 2 can be automated in the form of prefabricated modules or removed by hand in a simple manner from a roll and securely fastened to the metallic component 1.
- the transponder 2 Since the transponder 2 is arranged completely in the recess 3, it is ensured that no protrusion arises on a surface of the metallic component 1.
- the recess can be filled with an electrically non-conductive material.
- An at least partial filling with a dielectric material may also be desired in order to influence the connection 6 between the transponder 2 and the antenna and / or the radiation behavior of the antenna.

- the metallic component 1 can also be formed as part of other beverage containers.
- beverage cans or beverage bottles with transponders 2 can be provided in this way, in which the outer wall 33 is at least partially formed of a metallic material.
- the recess in the outer wall 33 is designed as an opening 5, it is important that the opening 5 is filled with a non-conductive material or sealed with a breakthrough 5 covering layer of non-conductive material to a possible escape of liquid from the Beverage keg 20 to be prevented.
- Fig. 15a shows a beverage keg 20 with a closure 25 (also referred to as a fitting) with an antenna structure for a transponder 2, while Fig. 15 shows a detailed view of the antenna structure of the closure 25 from Fig. 15a.
- the in the Antenna structure disclosed in FIGS. 15a and 15b is an alternative to the antenna described above, which is formed by means of the recess 3 in the metallic component 1.
- the antenna structure is formed by means of an annular member 27 made of conductive material. At a portion of the annular member 27, preferably an edge region, a contact 30 is provided, by means of which, for example via a coaxial cable 13, a connection with a transponder 2 is made.
- the annular member 27 has an interruption 29 formed of an electrically non-conductive material.
- the contacting 30 should preferably be provided on a region of the annular component 27 which lies opposite to the interruption 29.
- the annular component 27 comprises a conductor loop, which is arranged in an electrically non-conductive annular component.
- a planar element 28 of electrically non-conductive or conductive material for example of plastic or of metal, is provided, which is surrounded by the annular component 27.
- the presented here, built in the cap antenna structure can also be used in closures other beverage containers. However, it can also be used independently of containers or their closures as a separate antenna for transponder 2.
